Abstract

The invention discloses an earphone-type EEG collection device, which includes an ear canal electrode for collecting ear canal brain waves, and a locking position on the ear canal electrode is connected with a locking position on a metal connector to realize electrical conduction. The ear canal electrode is clamped on the shell to achieve the function of fixing, the metal connector is plugged on the circuit board and welded to the first through hole of the circuit board to realize electrical communication, and the circuit board is provided with a device for receiving data collected from the electrodes. signal and process the disposition circuit for that signal. The structure of the present invention is concise and compact, which satisfies the need to collect brain waves from the ear canal, and also satisfies light weight, small size, comfortable wearing, and the function of Bluetooth earphones, and controls the transmission distance of brain wave signals from the human body to the circuit board within a reasonable range. Within the range, the signal transmission distortion is small, the circuit board structure is stable, the signal processing stability is good, and the production is simple and the cost is low.

Description

Technical field

[0001] The invention relates to an brain electricity acquisition device, in particular to an earphone type brain electricity acquisition device. Background technique

[0002] At present, wearable brainwave acquisition devices on the market have different electrodes extending from the main circuit board and contacting different positions of the human body, and there is a special device for fixing the entire acquisition device on the human body, which leads to troublesome wearing. And too many additional devices will lead to a decrease in wearing aesthetics. For example, there are currently ways to extend several electrodes from the main circuit board. The electrodes and the main circuit board are made of elastically deformable materials, and the scalp is clamped from various directions through several electrodes to achieve a fixed effect; The design uses elastically deformable materials to clamp the head over a certain distance on the scalp like a headband. These ...
